"I read the script for the pilot and I thought, 'This is never gonna work' because it was so big and, you've seen the show - it's just so epic that you think, 'How are they gonna shoot this?' and even doing it, I go to work and I go, 'How the hell are they gonna do this?' because we have two full-sized units working, sometimes three, [and we shoot in] four different countries... It's a circus," Coster-Waldau recalled.

Coster-Waldau also discussed Game of Thrones's upcoming third season, which he described as "amazing".

"I can say this much: I love doing that show," he declared. "It's just amazing, the writing is amazing.

"When we started, I was just praying we would make it to season three because that was my - that was the season... where everything - a lot of great things happen."
